Oh, I see: it's because batch-native-compile runs the final
compilation phase in a subprocess.  But doesn't that mean the
non-default setting of comp-debug will not have its effect in this
case?

Btw, I find the doc strings of the various top-level native-compile
functions not very helpful when I need to understand under what
circumstances they run the compilation asynchronously.  I always need
to read the code, and read it carefully, to figure that out.  Can this
please be improved?
